ARTHUR J. MORSE, OF SALISBURY, CONNECTICUT, ASSIGNOR TO THE MORSF-KEEFERCYCLE SUPPLY COMPANY, OF SAME PLACE. A

SLOTTING AND SLABBING MACHINE.

SPECIFICATION forming part ofA Letters Patent No. 628,410, dated July 4,1899.

Application led August 10, 1897. `Serial No. 647,746. (No model.) a

To all whom. t may concern.'

Be it known that I, ARTHUR J. MORSE, of Salisbury, in the county ofLitchfield, in the State of Connecticut, have invented new and usefulImprovements in Slotting and Slabbing Machines, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

My invention relates to slotting and slabbing machines for use inmanufacturing nipples for bicycle-spokes or other similar devices; andthe object is to provide a machine that will operate on several nipplesor other articles at once, producing a somewhat different operation oneach, and that will operate upon said nipples successively.`

, To this end my invention consists in theA combination, in anipple-slabbing machine, of

a disk provided with chambers to hold the nipples, means to rotate thedisk intermit-` tently, a sliding bar carrying a rotatable spindle onone .end extending parallel with a face of the disk, two sets of cutterson the spindle to operate simultaneously on a pair of nipples, andsuitable means to reciprocate the sliding bar; and my invention consistsin certain other combinations of parts hereinafter described, andspecifically set forth in the claims.

In the drawings hereto annexed and forming a part of this specification,Figure l is the top plan view of my invention. Fig. 2 is the front sideelevation. Fig. 3 is the rear side elevation. Fig. l is an end elevationlooking from right to left of Fig. l.- Fig. 5 is an end view of some ofthe important movable parts in the opposite position from that indicatedin Fig. 4. Fig. 6 is an end View of the machine, looking from left toright of Figs, l and 2. Fig. 7 is a side elevation of the spindle orspindles carrying the slabbing-cutters. Fig. S is a section of thepresser-plate which holds the nipples in the disk, and Fig. 9 shows anipple before and after it is slabbed.

Referring specifically to the drawings, A is the frame of the machine,having forward extensions aand a for the sliding bar B to move on andrearward extensions b b for the sliding bar C to move on. Another pairof extensions c c and c" are above the extensions h and b to providebearings for the drivingshaft D, which carries a cam-wheel D' to movethe sliding bar C below it, and a cog-wheel E, which meshes with acog-,wheel E on a short shaft F, turning in bearings over the center ofthe frame A. The shafts D and F are parallel with each other and liewith their axes in the same horizontal plane. The shaft F also carries acamavheel F', which engages a roller B on the inside of the sliding barB t-o move the bar toward the disk G, which carries thenipples to be andin the process of being slabbed and slotted.

The disk G is secured on one end of a horizontal shaft G, which turns inbearings g g in a bracket G", secured to the front side of the frame A.

D is the driving-wheel on the shaft D.

The cam-wheel F' is designed to move the bar B longitudinally toward thedisk G once during each revolution, and a coil-spring d, connectedbetween the said bar and the extension, serves to retract the bar ordraw it away from the disk. The disk G is provided with a circularseries of holes which extend through it near its periphery to hold thenipples. Twenty holes are shown in the disk in the drawings, and theseholes are just large enough to admit the shanks of the nipples, whichhave the appearance of rivets, and are countersunk slightly to partlyreceive the heads. In order to hold the nipples in and to prevent themfrom turning while they are being operated upon, I provide a bracket H,having a curved arm secured by screws to a segment of a disk h, whichcarries a curved tension-plate h on the side next the disk in' the pathof the heads of the nipples. The tension-plate 72. is curved outward atthe receiving end to allow the heads to pass easily between it and thedisk. The construction of this segment h is shown clearly in Fig. 8 ofthe drawings. This view shows the plate h held in a groove in thesegment h by apair of curved strips h" 7L", screwed to the segment. Acurved plate t' is in the bottom of the groove to form a bearing for theends of a series of adj Listing-screws 7l' rbc., which pass through thesegment to increase the tenthe plate 7L and the plate i. The bracket I-Iextends horizontally and lies against the'rear side of the frame Aand isadjustable toward and from the disk G by means of screwsgl j, passingthrough short slots in the bracket.

The nipples are inserted by hand .in the disk, which revolves in thedirection of the arrow. (Shown in Fig. 6.) When-a nipple reaches a pointforty-five degrees above a horizontal plane extending through the axisof the shaft G, it is slabbed or made flat on a portion of two oppositesides, after which it is carried by the disk a distance of ninetydegrees, during which it is turned over onefourth, allowing cuttersmounted on the same spindle as the other cutters to slab or flatten theother two sides, thus forming a square section on the shank of thenipple for the application of a Wrench when it is turned on a spoke. thedisk about fifty degrees, more or less, farther it is then in positionto have its head slotted or recessed for receiving a screwdriver, asusual, and when it has been carried a few degrees fartherit is pushedout of the disk by a pusher L automatically with the other operations.

A brief description of the operations has been given before the partshave been fully specifically described to prepare for a clearunderstanding of the operation of said parts, which will be hereinafterfully described.

The end of the sliding bar B nearest the disk is made broad and isprovided with a pair of bearings c k for the spindle I of theslabbing-cutters I I, which are arranged in pairs for the purpose ofslabbing two sides at once. The cutters are of the usual formnamely,disks with serrated peri pheries--and they are suitably mounted to turnwith the spindle, and they are separated to allow the ends of theAnipples to pass between them.

I is a pulley in the center of the spindle and between the bearings k 7cfor the beltv which drives the spindle. The cutters I I rotatecontinuously, and when the disk is stationary the cutters aremade toapproach the disk and slab two sides of a pair of nipples. Then the barB, carrying the cutters, is retracted by the spring d, after which thedisk is revolved the distance between two nipples, which brings twoother nipples in position to be slabbed, when the bar and cutters areforced toward thedisk as before. The spindle for the cutters is dividedin the center, so that one or the other end may be removed withoutremoving the other. The inner ends of the spindle are lapped over eachother with' a flat bar Z between, which bar extends diametricallythrough the pulley, as shown in Fig. 7 of the drawings. I do not limitmyself to this form of connection, however, as it may be made in variousways. The spindles are held in place and in' their bearings by angulararms m m, secured to the bar and extending outward opposite the ends ofthe spindles, and ad justing-scrcws fm' 011/, passing After the samenipple is carried by through the ends of the arms and bearing with theirends on the ends of the spindle I', as shown clearly in Fig. l of thedrawings.

.The shaft G is rotated intermittently by means of a ratchet-wheel J onhe end opposite that carrying the disk G.- The ratchetwheel is providedwith as many teeth as there are holes for nipples in the disk, thenumber in this case being twenty. The recesses in the periphery of theratchet-wheel are shown square and are preferably made square in orderthat the disk may be held positively against movement in eitherdirection during the slabbing and slotting operations.

J is the pawl for turning the ratchet-wheel.

Said pawl is connected at one end with an upwardly-extending arm of abell-crank lever K, pivoted to the frame. The pawl J is adj ustableuniversally in a vertical plane by slots and screws. (Not necessary tobe specified.) The other arm of the bell-crank lever is connected by acoil-spring n with the base of the machine to carry the pawllongitudinally when released.

The pawl J is operated to turn the ratchetwheel by means of a roller t,carried on a short arm or projection 7o, extending from a sleeve 7.2" onthe drivingshaft,striking during each revolution ofthe shaft theupwardlyextending arm of the lever K. A stop-screw '0 is shown extendingthrough the frame'to engage 'the horizontal arm of the lever K and vertoo far. Another cam p on the sleeve operates a pawl or detentp, pivotedintermediate its length,which holds the ratchet-wheel against'movementduring each operation by means of a square lug on its free end enteringthe square recesses in the ratchet-wheel J. The pawl p is seated by aspring p".

M is the spindle, carrying the single cutter N on one end for slottingthe 1heads of the nipples after they have been slabbed. This spindleturns in bearings q q'on the broad end of the sliding bar C beforereferred to. The cutter N is on the opposite side of the disk from theslabbing-cutters.

Q is the pulley on the spindle M for driving the spindle. The head of anipple is slotted while two other nipples are being slabbed and, ofcourse,while the disk is stationary. Therefore the sliding bars B and Care moved by their cams simultaneously in opposite directions, the diskonly turning when the said bars are receding from it. A bifurcatedspring-plate N is secured on the end of the bracket I-Ito bear upon thehead of the nipple while it is being' slotted by the cutter N to hold itstationary, as clearly shown in Figs. 3 and 6 of the drawings.

The pusher L (shown in Fig. 2 of the draw-` IOO IIO

adapted to strike the end of a nipple and push it out of its aperture inthe disk.

I do not wish to be limited to the precise construction of parts shown,as it will be obvious that they may be changed Widely Without departingfrom my invention.
